Emisar D4 Mods

HELP!

Trying to flash my D4 to Anduril, but I can’t get AVRdude to run.

Every time I try running it the command prompt says “Does not have permission”. And a popup window appears saying the app is not allowed to run on my PC.

I installed AVRDude last week briefly. For the first 20 minutes it worked and behaved normally, but now the app won’t even run. Uninstalling and reinstalling didn’t help.

Using Windows 10. This is a home PC and I’m the only one who uses it. I have admin privileges and have no idea how this happened or why the app stopped working.

Any ideas? or suggestions for alternate programs that might run?

Unlikely this would help, but if you are anywhere near Santa Barbara you can swing by my place and program your D4. I a necessary parts and a pretty recent version of Anduril for the D4. Otherwise, your problem sounds pretty weird, the only thing I can think of is be try shutting of your PC and waiting a bit, then turn it on and try again.

Did you already trie to right click on the icon and then run as administrator?

I finally got my Lexel lighted TIR board installed in my D4. I like it!! Not easy to install, but not that much harder than flashing my D4 with Anduril.

awesome!

did u flash anduril D4 with activated aux output?

I think you are asking if I can control the aux light board with the e-switch. I can not. ToyKeeper gave me some tips how to change the firmware to be able to do that, but I decided to just use as is. The current draw of just the aux light board is 0.7mA. I am using a 1100mAhr 18350 cell, so it will go a couple months before aux board would draw the capacity significantly. This is my EDC light, so I am charging the cell every week or two, so I don’t see the need.

It’s bright enough to navigate around at night with just the aux lights on, at least to see if there is something in your path.

I glad I did this. :slight_smile:

0.7mA?

did you order the Aux Board with any special requests regarding the resistors or just as is?

oops, typo in the previous post that I corrected, thanks!

Lexel will let you pick whatever you want. My impression is each aux board is made to order.

Below is part of our chat via private messages:

_Lexel:
config is circle of 8 then 4 inner 2

sbslider:
Changed my mind on the colors a bit. The inner 2, would like those WW. circle of 4 purple. circle of 8 red/ice blue, with the colors mixed evenly (LED 1, 3, 5, 7 red, 2, 4, 6, 8 ice blue)._

The outer circle and middle circle are very close to the same diameter. Groups of 2 of the outers and 1 of the middle form a tight triangle, with 4 groupings around the board.

Most of what is visible in the not so great picture above is the warm white and ice blue. The purple and red did not really come out well in the picture. It looks much better in person I think, but the picture gets the idea across. It looks a bit different depending on the angle you look at it which I like.

I have one with green only and one other board with blue only.

so far none is mounted, as I am trying to get anduril compiled with aux enabled :slight_smile:

love the d4. switched mine from LH351D to Sst20 today. double the throw with just a minor dip in output. both 4000k high cri

switching over to sst20 sounds tempting . . . . .

It’s worth it, you get some decent throw and high CRI at the same time

only if you did not have high cri before. Both 219b/c as well as LH351D are available as high cri. I only use high cri for edc lights and headlamps :slight_smile:

but the added throw is nice

Well I own quite a few lights and some decent emitters already (219A/B/C in different taste, LH351B/D and some 3000K/4000K SST20…) and the SST20 are a really good compromise.
My D4 has 2*3000K and 2* 4000K and is my EDC for the winter.

I have two emitters XP-L HI V2 3A and two 5D. Not sure what the CRI of them are but I like the light they produce.

Can anyone explain the difference between 219s and the LH351s? Are the Samsung LEDs more efficient?

there are different Samsungs. LH351C and D. D has bigger die like XPL.

they are more efficient. But 219b high cri has the best tint + color imho.

sst20 is nice as well, but the 4000k high cri is no match in tint and color quality to 219b

1. The LH351D 90CRI is the most efficient high CRI LED, but is more geared towards flood.

2. The 219Cs are the easiest LEDs to find.

3. The 219Bs have the rosiest tint and equal color rendition. It doesn’t actually reproduce the colors the most accurately though, and is the least efficient LED here.

4. The SST-20 is the throwiest high CRI emitter, has better color rendering than the 219C and LH351D, and is the most accurate emitter in terms of color rendition.
In fact, if it had a rosy tint like the 219B, the 219B would immediately be obsolete. It looks excellent regardless, but most people here prefer rosy tints rather than pure white tints, or very slightly green.

SUCCESS!

My Emisar now runs Anduril with enabled Aux for D4. Also Blinkies have been reduced to candle + lightning storm :slight_smile:

Thanks for the tips pointing me in the right direction.
